" Application filed November 5, 1920. Serial To aZZ 10/10/22 it may concern:

tie it known that I, CARL W. CARLSON,

citiaen of the United States, residing at Beloit, in the county of Rock,State of Wis 5 cousin, have invented a new and useful Fuse Plug Puller; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which, it appertains to make and use the same.

The invention has for its object to provide a device of this character which may be used to obviate the necessity of an electrical worker crawling through various high tensioned wires which is exceedingly dangerous and often results fatally.

A further object is to puller comprising a handle at one end thereofa bifurcated hooked mem her adapted to engage over the knob of a provide a plug plug and held in frictional engagement with said knob by means of a spring actuated -pivoted tongue which is right angular shaped 5 and has one of its arms pivotally connected between the hooked members and its other arm extending outwardly in the direction of the ends of. the hooked members and forming means for engaging the outer end of the knob for holding said knob and plug as the same is being removedor replaced. The pivotal point of the tongue being positioned substantially centrally of the engaging point of the plug knob with the tongue, thereby on the knob when the same is being replaced, and also preventing the tongue from being forced downwardly against the action of its spring when an inward pressure is applied to the plug, thereby insuring the proper and positive holding of the knob during a replacing or-removing operation. 7

With the above and other objects in view the invention resides in the combination and .-5 arrangement of parts as hereinafter set forth, shown in the drawings, described and claimed, it being understood that changes in the precise embodiment of the invention may be made within the scope of what is claimed without departing from the spirit of the invention. 1

In the drawings Figure 1 is a side elevation of the plug remover showing the same in position on the knob of the plug.

relates to plug pullers and member having pressure to be applied Patented Mar. 28, 1922. No; 421,986.

Figure 2 is a front elevation of the plug removerwith the handle removed. Figure 3 is abottom plan view of the plug remover with the handle removed.

iteferring to the drawings, the numeral 1 designates a conventional form of electric plug, and 2 a knob carried thereby, which knob is connected to the plug 1 by meansof the shank Plug removers heretofore in use have not been positive in their operation and the chief fault of the same has been found that plugs are often dropped when being placed in position, or not held positively enough to allow the same to be forced inwardly. The consequence has been that plug pullers of this character have fallen into disuse and operators have resumed the dangerous and often fatal 0p-' eration of removing plugs by hand.

The plug puller comprises a handle memher 4, preferably formed from wood and provided with a ferrule 5 for preventing the same from splitting. Disposed in the end of the handle member 4 isthe shank6 of a metallic member which metallic member extends outwardly and is bent as at 7 so as to form the angularly disposed portion 8, said member 6 being bifurcated as at 9 thereby forming two angularlydisposed portions 8. The angularly disposed portions 8 merge into spaced hooked members 10, the ends 11 of which are substantially horizontally disposed and are adapted to engage the inner face of the knobs 2 of the plug when the shank 3 of said plug is passed between the portions 11 that is during a plug removin or replacing operation. The knob 2 is held in frictional engagement with the inner edges of the ends 11 by means of the curved arm 12, which is angularly disposed in relation to the inner sides of the portions 11 and is'held in engagement with the outer face of the knob 2 by means of the leaf spring 13, which leaf spring is secured by means of screws 14 to the shank 6 and has its free end 15 in engagement with the under face of the arm 12. Extending and at substantially a right angle to the arm 11 is an arm 16, which arm is disposed between the angularly disposed portion 8 of the shank 6 and is pivoted on a pin 17, said pin forming a pivotal point on whch the arms 12 and 16 rock against the influence of the leaf spring or under the influence of the leaf spring. The pivotal pin 17 is located downwardly i substantially beneath the central point of the plug 1, thereby preventing downward pivotal action of the arm 1 is being forced inthe direction of'the arrow a 'Hovvever after the plug has been properly positioned the hooks 10 may be easil detached from the knob 2 by a movement of said hook inthe direction of the arrow 1). lVhen the plug is in position and it is desired to remove the same, the portion liflofthe arm 12 is placed in engagement with the outer face of the knob 2 and the arm 12 rocked downwardly against the action of the leaf spring sufiicient-ly moved to allow the knob 2 to pass under the horizontal arms 11, and the shank 3 between said arms until the knob 2 assumes the position shown in Figure 1', at which time, the plug may be easily and quickly removed byanoutward pull on the device as a, whole.

The invention having been set is claimed' as new and useful is l1, An electric plug remover comprising a handle member, hooked members carried by said handle and spaced from each other and adapted to engage over the head of a plug and a spring actuated tongue pivoted to'the hooked members and cooperating with the head of the plug for holding the hooked members in engagement with the plug duringa plug removing operation.

- 2. An electric plug remover comprising a handle member, a plug head engaging hook carried by one end said hook comprising spaced arms formed by a bifurcation, said arms being substantially at a right angle to the handle member and adapted'to engage over an enlargment of a plug, and a spring actuated tongue disposed within the hookof the hooked member and pivoted to said hooked member and 12 whenthe plug 13, until said arm is members, and a spring 7 'membe" in the forth what of the handle member forming means for engaging the enlargement of the plug and holding the plug during a plug removing operation.

3; An'electric plug remover comprising a handle member, spaced hooked members carried by said handle member at one end thereof the ends of said spaced hooked members terminating in arms substantially right angularly disposed in relation to the handle member, a right angularly shaped member having the endaofone of its arms pivoted between the hooked members adjacent the end of the handle, the other arm of said right angularly shaped member being in substantially parallel relation to the ends ofjthe hooked members and adapted to engage the head of a plug and in engagement with the ends of the hooked for normally -forcing the plug head engaging'arm oi: the annular direction of the ends ofthe hooked members.

4. An electric plug remover comprising-11 handle member, spaced hooks carried by said handle memberv and terminating 1H arms substantially right angularly disposed in relation to the handle member, a right angled member having 'theend or" one'oi'i its arms pivoted between the, spaced hooks and its other arm substantially parallel disposed in relation to theends of the spaced hooks, and spring means for normally forcing said last named arm in the direction of the ends of the spaced hooks. a

In testimony whereof I have signed my name to this specification in the presence of two. subscribing witnesses. v
